Installation and service must be performed by Qualified Service Personnel Only.
WARRANTY:
Factory warranty (available on web site) does not apply to units improperly installed or improperly operated.
Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of
most operating problems.
Excessive water hardness causing a lime/scale build-up in the heater and/or on the immersion heating
elements is not the fault of the equipment and is not covered under the manufacturer's warranty. (See Water
Treatment and Water Chemistry)
Do not energize electrical system before heater is completely filled with water. Damage caused to the
immersion heating elements by dry fire is not covered under the manufacturer's warranty. Follow start up
procedure in the manual. Water heater corrosion and component failure caused by air-borne chemical vapors
is not covered under the manufacturer's warranty. Corrosion damage caused by current leakage due to
improper grounding of electrical systems or electronic components to the storage tank and related piping
is not covered by the manufacturer's warranty. Under no circumstance will the manufacturer be liable for
consequential damages resulting from the installation or use of this equipment. Correct installation procedures
and local codes must be adhered to.
Improper Installation, Adjustment, Alteration, Service or Maintenance can cause injury or
property damage. Refer to this manual. For assistance or additional information consult a qualified
CHECKING EQUIPMENT:
This manual supplies information for the installation, operation and servicing of the appliance. It is strongly
recommended that this manual be reviewed completely before proceeding with an installation. Upon receiving
equipment, check for signs of shipping damage. Pay particular attention to parts accompanying the water heater,
which may show signs of being hit or otherwise being mishandled. Verify total number of pieces shown on
packing slip with those actually received. In case there is damage or a shortage, immediately notify carrier.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDER WATER. THE POSSIBLE
DAMAGE TO A FLOODED APPLIANCE CAN BE EXTENSIVE AND PRESENT NUMEROUS
SAFETY HAZARDS. ANY APPLIANCE THAT HAS BEEN UNDER WATER MUST BE REPLACED.

WARNING To minimize the possibility of serious personal injury, fire or damage to your appliance, never violate the following safety rules: 1. Always keep the area around your appliance free of combustible material, gasoline and other flammable liquids and vapors. 2. -
Page 6: Clearances
6. The floor on which the appliance is installed must be capable of supporting the total weight of the water heater when completely filled with water. Combustible floor locations may be used. Maintain required clearances from combustible surfaces. 7. The appliance must not be installed on carpet. 8. -
Page 7: Mounting
Maintain minimum specified clearances for adequate operation. All installations must allow sufficient space for servicing the electrical components, water pipe connections, piping and other auxiliary equipment, as well as the appliance. MOUNTING: The water heater should be mounted to the floor following applicable architectural and local code requirements or accepted standards for the specific site and model purchased. -

hand hole for ease of inspection, cleanout and service. An optional manhole may be specified for a greater ease of inspection. The interior of the storage tank is glass lined and fired insure a molecular fusing of glass and steel to protect the steel base metal against corrosion. A magnesium anode(s) is standard to enhance the protection of the substrate metal of the tank. - Page 9 1. Use copper conductors only. All wiring between the appliance and field installed devices shall be made with copper wire suitable for at least 75° C (167° F) temperature rating. If the wiring from an old water heater installation was aluminum, replace the old wire with copper wire. 2.

CAUTION: DO NOT CONNECT THE WATER HEATER TO AN IMPROPER SOURCE OF ELECTRICITY! CAUTION: Never turn on the electric power or attempt to use this electric water heater unless it is completely full of water. Water must flow from the hot water faucet before turning electrical power "ON." Operation of a water heater without a completely filled tank may result in serious damage to the appliance and heating element burn out. - Page 11 • Immersion thermostat (one per 54kW of input as standard). • 180°F (82.2°C) temperature operation is possible to provide water for sanitizing applications. • 150 PSI • Insulated to meet the latest edition of ASHRAE 90.1 energy efficiency standards. • 3 year limited warranty provides protection against failure of tanks due to defects in material and workmanship.

Page 12: Contactors
A main power terminal block is provided for field connection of the branch power supply to the electric water heater. All internal power circuits to the immersion heating elements are connected to the load side of the main terminal block. The line side of the terminal block has individual lug type connections properly sized for the recommended copper field wire size. -
Page 13: Immersion Thermostat
WARNING: HAZARD OF ELECTRICAL SHOCK - Before opening the electrical access panel to adjust the thermostat or servicing the water heater, make sure the electrical supply to the water heater is turned "OFF". Failure to do this could result in death, serious bodily injury or property damage. IMMERSION THERMOSTAT (S): This water heater uses an immersion thermostat(s) to activate magnetic contactors allowing current to flow to the immersion heating elements. - Page 14 Allow a few days of operation at the setting to determine the correct temperature setting consistent with your needs. CAUTION: Higher stored water temperature increases the ability of the heater to supply desired quantities of hot water, however remember: Hotter water increases the risk of scald injury. Setting the temperature selector dial higher provides hotter water, which increases the risk of scald injury.

TEMPERATURE ADJUSTMENT: 1. Tum "OFF" the electrical power to the water heater. If the power disconnect point is out of sight, lock it in the open ("OFF") position and tag to prevent unexpected application of power 2. Open the water heater's electrical access panel 3. -
Page 16: Temperature Limit Control
HIGH WATER TEMPERATURE LIMIT CONTROL: The unit is equipped with a fixed setting manual reset high water temperature limit control. The water heater temperature limit control has a fixed limit setting of 195° F (90.6° C). If water temperature exceeds the limit set point, the limit will break the control circuit and shut down the unit. -
Page 17: Low Water Cut-Off
The "O" ring element gasket must be replaced with a new gasket when an element is removed for inspection, cleaning or replacement. SAFETY DOOR INTERLOCK: The optional safety door interlock is an electrically operated locking pawl that is energized when main power to the water heater is turned "ON."... -
Page 18: High Water Pressure Switch
HIGH WATER PRESSURE SWITCH (OPTIONAL): A high water pressure switch is available as an option on this water heater. A water pressure switch is used to monitor the water pressure in the water heater storage tank. If the water pressure rises above an adjustable set point, the control circuit is opened and operation of the water heater is shut down. -
Page 19: Alarm Bell
SHUNT TRIP DISCONNECT (OPTIONAL): Shunt trip disconnect provides a power disconnect upon a control sensed malfunction via a circuit breaker installed in the main power supply to the water heater. The circuit breaker is shipped as a separate item that must be field installed. The water heater 120 VAC control circuit provides a feed to the circuit breaker that will shut down main power on either a low water level condition (if equipped) or high water temperature. -
Page 20: Filling The Water Heater
DANGER: Full power is present whenever the cabinet door is opened, even with the pilot switch(es) turned off. THERMAL EXPANSION OF WATER: A relief valve that discharges periodically may be due to thermal expansion in a closed system. Many water systems are equipped with pressure reducing valves, check valves or back flow preventers which may cause the water system to be closed. - Page 21 NOTES...
